What is IVT?

IVT is a VT220 terminal emulator for Windows NT/2000/2003/XP/Vista/7/8/10,
that can set up a secure
(Kerberized) telnet,
SSH,
RLOGIN, NetBios or serial connection to a remote host.
In other words, you use it to get a shell prompt on a remote Unix-like machine.

It supports multiple (tabbed) sessions of different types in a single window and has
a scripting language to automate standard tasks (such as logging in and creating
multiple sessions).

IVT can do all things that PuTTY can do, and many more things besides!

It can automatically log your sessions to a file, optionally with timestamps for
every line so you have a record of exactly what happened and when.

If you administer (or use) a large network with many machines, IVT allows you to
initialise your working environment with only a few mouse clicks.
Logging in to an array of hosts with either Telnet, Kerberized Telnet, SSH or even
serial modems, starting programs there, automatically analyzing the output,
customising the keyboard and screen (different key-mappings and colors per host
and/or session if you want to) is all easily achieved.

If you use a PC to access remote hosts and you care about fast,
accurate VT220 terminal emulation
with a large tabbed screen, multi-session, color support, fast copy/paste etc. because
you use Unix text-mode applications such as VI, EMACS, or Midnight
Commander, then IVT is a program designed for you.
If you want secure authenticated login, you can use SSH or the Kerberos V5
authentication and encryption support built into the commercial version
of IVT (available from
SoftwareVoordelig webshop).
Version 24.0 of IVT adds
GSSAPI authentication
(integration with Active Directory).
Once you get used to creating sessions with a few clicks and switching between
10, 20 (or even more) parallel
sessions without losing track, you'll wonder how you ever got along without
it :-)
I have worked in environments with many hundreds of
Unix machines, and IVT is tailored to make life in such environments easier.

New in version 24.0 of IVT (November 2014):

GSSAPI/SSPI over SSH support.
When you run IVT on a Windows PC that is part of an Active Directory
domain (or Kerberos Realm), you can login without using passwords, on hosts that
are part of that AD domain.

Better integration with MIT Kerberos for windows (must now be installed
separately from the
MIT download site).
Same goes for WinSCP, please install separately.

New HIGHLIGHT feature: when text
matching Perl-style regular expressions
appears on screen it can be highlighted and actions can be associated with such
highlighted text.See here for an example,
where error messages from a compiler are recognized, and highlighted.
When clicked, an IVT script automatically starts
your favourite editor on the proper file and line.
This can be used to recognize arbitrary patterns and start arbitrary actions
either automatically, or when the user clicks on them.

One standard HIGHLIGHT is the one for URLs: any URL displayed on an IVT
session is made bright-blue underlined and starts a browser when clicked (so it looks
like a link and acts like a link).

Integration with regular expressions, Perl style.
Matching and replacing strings, waiting on host data and highlighting texts
can als be specified in regular expressions using the powerful Perl syntax.
Searching scrollback data now also supports regexp based searching.

Smart paste: common
characters found in Word documents such as left-quote,
right-quote and various others are automatically translated by IVT upon pasting
into their logical ASCII equivalents so they are recognized by the Unix Shell.
The upshot is that copy/pasting Shell commands from a Word document simply works.

Many improvements to file transfer: Just
drop files on the IVT window while the session is at the Shell prompt and
IVT will transfer the files.

Lots of new functions added to the IVT scripting language.

Many improvements to the NEWWIN option, where IVT does not open a session in
a new tab, but opens a new window instead.

Dozens of other minor extensions, bugfixes and improvements.

The versions you can download here are a free 30-day evaluation versions.
After the evaluation period expires, the security features cease to function and
various limits are imposed on other features.
To restore full functionality, please obtain a licence from
SoftwareVoordelig.nl.

The older versions of IVT called "Light", "Telnet only" and "Freeware" have been
discontinued. The memory and diskspace limits that made these dressed-down versions
necessary no longer apply. The "Secure Access" version has all functionality
combined into one package.

The following files and versions of IVT are provided for download (all run on
Windows NT/2000/XP/2003/Vista/Win7/Win8).
The "Installer" column refers to files with a full Windows install wizard.
The "Upgrade kit" refers to ZIP files with all the latest files, which you can use to manually update an existing (modified) configuration.
The highlighted cell below is for a self-unpacking, self-installing demo version of IVT.
It is the full version, but requires no administrator privileges to get IVT up and running.

These versions are available as 32-bit and 64-bit applications.
Make sure you download a version compatible with your version of Windows
(see this Microsoft site
for more information on 32/64 bit Windows).
